}Re-fit entity matcher model
Required capabilities:
entitymatchingAcl:READentitymatchingAcl:WRITE
Creates a new model by re-training an existing model on existing data but with additional true matches. The old model is not changed. The new model gets a new id and new external id if newExternalId is set, or no external id if newExternalId is not set. Use for efficient re-training of the model after a user creates additional confirmed matches.

}Authorizations
Access token issued by the CDF project's configured identity provider. Access token must be an OpenID Connect token, and the project must be configured to accept OpenID Connect tokens. Use a header key of 'Authorization' with a value of 'Bearer $accesstoken'. The token can be obtained through any flow supported by the identity provider.
Body
- Option 1
- Option 2
The ID of the original model.
1 <= x <= 9007199254740991List of additional confirmed matches used to train the model. The new model uses a combination of this and trueMatches from the orginal model. If there are identical match-from ids, the pair from the original model is dropped.
1 - 2000000 elementsA pair of source ID and target ID, that indicates a match between two entities in the source and target spaces. Internal and external IDs are supported.
- Option 1
- Option 2
- Option 3
- Option 4
